This is a sad story, several pieces in the photos are clearly barely different from 1960's and 1970's designs for Skrdlovice by F. Vizner, some later produced by Beranek glass. Not only that, but the people who run Princ know and have worked with Mr Vizner before, producing some new designs with him about ten years ago, with his agreement. Mr Vizner seems to have been a generous man who was very supportive of them as a new Czech glassworks. To do this now, selling pieces near identical to these famous Skrdlovice designs in Prague, without his consent or recognition, clearly deliberately omitting his role in originating the designs, is very sad and even more negatively, at a time when it is quite well known he is not in great health. Pretty rough... I hope justice is served,
